This would be big for us. When we initially looked at the problem of sharing or keeping a large number of files in sync, the prospects were dim. DRBD? etc. So we ended up using Gluster. Gluster has been temperamental at best. We've been able to move some data out and into elasticsearch, but not all. So, I've nudged my AWS rep and signed up already. Reliable NFS is good for me.

We couldn't find a solution either, so we built a posix filesystem with S3 backend backend that is easy to run and scale. If you want to give ObjectiveFS (https://objectivefs.com) a try, I'll be happy to hear your feedback.
